B o-it known thatI, ELEAZER'B. ROBERTS, of the city ofsRochester, in the State of New York, have invented anew and useful Improved Cultivator ands-I do hereby declare that the following is a full, clear, and exact description thereofqeferchce being had to the accompanying drawing, making part of this specification, in

t Figure 1 is a side view with my \veedcut-ter attached.

Figure 2a a roan View with my rotary hoes attached. Figure '3 is a top,view ofthe weed-cutter as, detached from the cultivator. Figure .4 is a topview of'the rotary hoes detached from the cultivator.

Lilre'lettors indicate corresponding parts. V v p This invention consists in constructing a cultivator, with weed-cutters or revolving hoes, the one to be substituted for the other in thediherent operations of cultivating and weeding corn, potatoes, ac.

- To onableothers tomahe and use my invention, I will describe its construction andoperation.

l suspend asuitahle frame,.A, 'on th e axle of a,wheel, B. This wheel supports the frame and itsattachmerits, and also-serves to give motionto'a weed-cutter, C, or rotating'hoes, ,D, to be attached on the end of the frame A. 0n:each end of the axle of the wheel B, I keya bevel-wheel, K, which gears into a bevel-pinion, B on a shaft, G, on each side of the wheel B. The shaft G extends back to the rear ofthe machine, and on the rear end I put a bev,el-wheel,- H, which gears into the pinion I on shaft A, which carries the weed-cutters O or rotating hoes D. The shaft-A issustained by a journal-box, K, fastened to a slotted arm, M, which isifastened on the rear of the framehy bolts. The top of the shaft Ais inclined fOIWMd BHd the slotted arm M is made inthe. form ot'a segment of a circle togive the rotary hoes any desired angle laterally to the surface of the ground. The weed-cutters G areiiiadc invfotm'as shown in figs. 1 and 3, and as many as are desired are fastened to a head'that is'held to its place on the shaft A, by a'set-screw, or other suitable device, when intended for use, i The rotary hoes are madc'in the form as shown in figs. 2 and 4, and put on the shaft A in a similar manner to the weed-cutters; On the bottom' of the frarne A, on each side of the driving-wheel B, I bolt a cultivatorv tooth, 'P, In front of thc wheel-I put a-doub'le cultivator-tooth, R. I also attach to the top of the frame two handles in front of thcwheel B, whichextcnd back as far as will be convenient for use to guide the cultivator; I The motleof using this machine is: On first going, over the ground planted with potatoes, corn, 850., the weed-cutters are attached to theshai't A, whichfbeing inclined forward at the top, causes the cutters to enter the ground as they revolve tothe front, andJlea-ve it as they pass to the rear, as shown in fi gi 1. On'the second c'ultiv'ating, the rotary hoe'sjare is'ubstitutedfor the weed-euttersi The revolving hoes can be placed at any .-desire(1 angle to thef'surfaceof the 'ground Q-laterally, by means of the slotted arm M, as shown in fig. 2, for the purpose of throwing the dirtup to form any desircdshaped hill around the born, &c., 01 to-add as much soil to the hill as i si requiredl l The o'peratijo'n'ot this combined cultivator and eed cutte r orjrotary hoes is such that when the weed-cutter is attached, the revolving jwheel B gives motion to .theshaft G, thereby imparting motion to the shaft A, and

revolves the weed-cutter- Qf 'The cultivator-teeth ploughing the ground the weed-cutters separate the weeds,-

ffromtheir mas.- Then, on taking on the weed-cuttcrs and putting on the rotary hoes, the soilis gathered to thccorn, orpotatoes, &o., as*required, and, the weeds are brought to the-top of the ground to die. This machine docs awaywith hanrLhoei-ng entirely. The wheels Kmay be made to move on the axle inand out, and the outsidesoi: the frame nlso'may be made to move in and out by adjustable bars at each end to regulate the distancebe tween the cutters or hoes, as eitl1er;arc muse." i

I What-I claim as 'my invention, and desire to secureL'etters Patent, is,-

1. Thempplication, to'cultivators', of,rotary weed-cutters hung ona verticalshaft, and operating substantially in the mannexhereinshown and described, and for the purposes s'etiorth.

' '2. The application, to cultivators, of rotating hoes hung oust-vertical shaft, and operating substantially the'mnnnerhereiu shown and described, and for the purposes set forth.

' 3. The'arrangement of the arm M, in combination with the rotary hoe D, substantially in the manner and for the purposes herein shown and described.
